High fuel price coupled with the requirement to reduce the use of fossil fuels has created the interest to use low calorific value gases. Fuelling lime kilns with renewable fuels to displace fossil fuel is not a new idea and has been subject of many studies and projects. Various alternative renewable fuels have been introduced or studied for use in lime kiln including Wood pyrolysis oil, Waste Oil, Chipped tiers and Solid fuels (i.e. Residue Derived Fuel - RDF). A new idea is the application of synthesis gas in lime kilns where the gas originated from RDF feedstock. The synthesis gas, also known as “Syngas”, is generated with a plasma gasifier fed with RDF. Raw Syngas resulted from a plasma gasifier is free from tar and has low dust load in comparison with the other gasifier types (circulated fluidized bed and bubbling fluidized bed), but still other contaminants (i.e. ammonia, chlorine, heavy metal and dust) in Syngas have to be polished out before introducing into the lime kiln. To launch renewable Syngas fuel, the raw Syngas generated from plasma gasifier must be cleaned from contaminants to meet process requirements and pollution control regulations.
This paper discusses about plasma gasification process simulation, cleaning scheme development to mitigate contaminants in raw Syngas to produce clean Syngas also technical issues due to change over from existing fuel gas to syngas fuel.
